Sezinso umsebenzi umshikashika imperceptible

Asazi ngokugcwele yonke imisebenzi zonke izinhlaka. Izinso nazo akuyona elula njengoba kungase kubonakale kanjalo. Nakuba umsebenzi oyisisekelo izinso ezaziwayo. Ezinye zazo nazi ngisho abantu kude imithi, nalo lonke abafundi baziswa kuphela - odokotela esizayo, izazi zezinto eziphilayo kanye bezilwane. Sakhiwo umsebenzi izinso wafunda ngokuningiliziwe at iminyango abafanele. Thina sizogxila kakhulu imisebenzi.

Hhayi umsebenzi kunazo owaziwa we nezinso iwukuhlale asidi njalo evamile igazi. Yiqiniso, umzimba obhekene inqubo eyinkimbinkimbi ezinjalo ngeke izinso eyodwa kuphela. Futhi ingxenye umsebenzi ewela ukukhanya. "Veda" zakamuva ku ukulethwa igazi-carbon dioxide. Kodwa izinso reabsorb Bicarbonate kusukela umchamo futhi secrete hydrogen ion ku umchamo, ngakho ukunciphisa asidi yegazi.

Futhi, hhayi zonke izinsuku sizwa umsebenzi kwezinso, ukulawulwa plasma osmolality. Buthule, ebumnyameni abakwenzayo umsebenzi wangempela yokugcina inani electrolyte egazini evamile. "Induna ngokushesha" kule okukhethekile izinso - hypothalamus. Uyakwazi ukubona ukwanda electrolyte egazini futhi unike isibonakaliso indlala pituitary. Ngenxa ukhiphe i-hormone antidiuretic, elibangela izinso ukwenza umchamo kanzulu xaxa, ukuletha amanzi amaningi e-umchamo. Ngakho, i-electrolyte ziboniswa, futhi amanzi ngaphezulu. Ngenxa yalokho, i-ratio solute namanzi - kuphela futhi iba evamile. i-hormone Antidiuretic uyakwazi okwenza abanye izingxenye nephron permeable ngaphezulu emanzini futhi ebuyiselwa igazi kokuba elicwengekileyo.

Lokunye lokubaluleke kakhulu umsebenzi ukulawulwa igazi by izinso ingcindezi. Yebo, benza lo nokuthi. isiqondiso eside yokucindezelwa izinkomba - izinso ibhizinisi. Lokhu umsebenzi obalulekile izinso emzimbeni womuntu esanda basingatha kakhulu nangodokotela bababhekene nezifo zenhliziyo kanye nezifo zenhliziyo - main "umbulali" abantu ngokulinganiswa ayemncane. Ukubuyela zokulawula umsebenzi kwezinso. Ngo umkhuba it is ezalethwa synthesis renin, esithinta molecule amaningi indlela ka-sodium chloride eziqukethwe igazi. Le nqubo ihlanganisa hormone ezifana angiotensin futhi aldosterone, futhi isikimu wezenzo zazo luyindida kakhulu. Kodwa ekugcineni kubuswa ngevolumu plasma, futhi lokhu kuthinta blood pressure. Yingakho "umongo" ukuphuza isisu, Nokho, ngempela ngesikhathi esifanayo esimisiwe izidakamizwa potassium-engashiyi, ngoba isisu ngokuvamile musa ukuhlukanisa phakathi electrolyte, futhi ngaphandle ngokwanele potassium inhliziyo kubi.

Futhi isici esithakazelisayo kakhulu iyona kwezici erythropoietin hormone. nesithakazelo ngokukhethekile le hormone, abasubathi. Iqiniso liwukuthi ngoba kwale hormone kwandisa umoyampilo abathwali - erythrocyte gemoglobinsoderzhaschih. Uma izinso akuyona i-oksijini eyanele - beqala kukhuthaza ukukhiqizwa kwamangqamuzana egazi abomvu. Ngakho-ke, ngaso sonke isikhathi uma ungenayo i-oksijini eyanele ukuqeqeshwa, izinso zakho ziqala synthesize erythropoietin, futhi ngemva kwesikhashana lapho kufika umphumela ukuqeqeshwa - nokwenze isibalo umoya-mpilo egazini.

Futhi ukuqedela Ukubukeza kwethu umsebenzi okukhiphayo imfucuza, eqinisweni, umsebenzi obaluleke kunayo yonke nezinso. Sidinga amaprotheni impilo, kodwa imikhiqizo umzimba walo - ubuthi ezinamandla kakhulu. Kancane ukuhoxisa namathumbu abo, kodwa okuningi uyaqhubeka share izinso. Kuyinto ba - abasebenzi ubumsulwa, abasebenzi ngokungakhathali, abenza evamile imvelo yethu yangaphakathi for ukusebenza ngendlela efanele. Kuyinto ukusebenza kwalesi umsebenzi angaphansi kwemithetho amadivayisi nephron - iyithimba kwezitho zangaphakathi of msulwa. Inqubo igazi ukukhululwa kwe "ukungcola" ezimbili-esiteji, kuqala ehlungiwe cishe kuyo yonke indawo, baphindela emuva, lingene egazini. Futhi kuleso naleso sigaba kuneendlela zokulawula nzima.

Avamile umchamo ukuhlolwa - izinyathelo okungenani sikwazi ukuthatha ukunquma isimo nezinso. Asikho isidingo indiva impilo lezi zisebenzi abasha.
